Stockton lunch on a Monday? quick help needed

A group of us are meeting in Stockton tomorrow for lunch...mainly because its central and one of us lives there (My friend from Hawaii is visiting relatives from the east bay and I figured Stockton was half-way, plus our other friend lives there....).

He asked ME if I had any preferences...so any suggestions? Among the ethnicities represented in our little group of six are Chinese, Japanese, Mexican, Indian, and then me....so ethnic restaurants would be fine if they are reasonably authentic.....

I think the Hawaiian chowhounds would most likely appreciate Mexican, as that is the cuisine they probably doesn't get as much of in the islands. But then again, one of them is Mexican and they have been staying with his family......
